6.4 DDLM_Set_Prm
When the system is turned on, configuration data set by the operator
is sent to the absolute encoder by the controller (DDLM_Set_Prm
mode). Parameters transmission depends on the configuration
chosen by the operator. Customarily data is sent automatically while
data setting is carried out through a user's interface available in the
controller's software (for instance, STEP7, see section "5.1
Configuring the encoder via Siemens STEP7" on page 14).
However sometimes it is necessary to set some bits and bytes
according to the working specifications you want to set.
Data transmission is carried out according to the specifications of the
encoder profile, as shown in the following tables.
